Campaign Day Management: How a Partner Runs 11.11 and 12.12 for Your Store

Campaign day management is the planning and live operation of a marketplace store through a mega sale such as 11.11 or 12.12. A partner handles campaign nominations, pricing and vouchers, ad budgets, stock allocation, live monitoring, chat and dispatch, so the store sells more without breaking stock levels or shipping deadlines.

 

Double-date sales are where many Singapore stores make or lose their quarter. Orders arrive in a few hours, prices change by the minute, and a single late batch can cost penalty points that block you from the next campaign.

 

This guide explains what campaign day management actually involves, the timeline a partner works to, and how the work splits between you and the team running it. It draws on how uParcel's CMOS (Complete Marketplace Outsource Solution) runs store operations, fulfilment and delivery as one chain.

 

 

What does campaign day management cover for a marketplace store?

It covers five workstreams: commercial planning (which products, what price), platform setup (nominations, vouchers, ads), stock and fulfilment readiness, live monitoring during the sale, and the post-campaign wind-down. A partner owns all five to a single plan, so pricing decisions and warehouse capacity never contradict each other.

 

Most sellers treat 11.11 as a marketing event. In practice, it is an operations event with a marketing front end.

Workstream	What the partner does	When
Commercial plan	Picks hero SKUs, sets discount depth, models margin after platform fees	5 to 6 weeks before
Platform setup	Submits campaign nominations, builds shop vouchers, bundles and ad campaigns	3 to 4 weeks before
Stock and fulfilment	Allocates stock per channel, books warehouse and courier capacity	2 to 3 weeks before
Live operations	Watches sales, stock, ad spend and chat in real time; fixes issues fast	Campaign window
Wind-down	Clears backlog, handles returns, reports results, resets prices	1 week after

 

Each row depends on the one above it. A voucher that drives 3x the expected orders is a failure if the warehouse planned for 1.5x.

When should 11.11 and 12.12 preparation start?

Start about six weeks before 11.11. Platforms open campaign nominations weeks ahead, nominations close before the sale, and products generally cannot be added once the window shuts. Six weeks gives time to set prices, clear nominations, receive stock and brief the warehouse, with 12.12 planned in the same cycle.

 

Here is the working timeline a partner typically follows. Treat the week counts as a planning guide, since each platform sets its own nomination windows.

 

1. Six weeks out: pick the range. Choose hero products, bundles and clearance lines. Check margin after commission, transaction and shipping fees (our upcoming guide to Shopee seller fees in Singapore breaks these down).

2. Five weeks out: forecast and order stock. Use past campaign data where you have it. Overseas brands need extra lead time for inbound shipping and customs.

3. Four weeks out: submit nominations. Enter products into the platform's campaign sessions and build shop vouchers and bundle deals.

4. Three weeks out: fix listings. Update titles, images and variations so campaign traffic converts.

5. Two weeks out: lock capacity. Confirm packer shifts, packaging stock and courier pickups.

6. One week out: dry run. Test voucher stacking, check stock sync across channels and set ad budgets.

7. Campaign window: run live. Monitor every few hours, with a named owner for each issue type.

8. One week after: wind down. Clear backlog, process returns and review results before 12.12 setup begins.

 

Overseas sellers restocking from abroad should also budget for import GST on campaign stock. Our upcoming explainer on GST on imported ecommerce stock covers when it applies.

 

How do campaign nominations and pricing work on Shopee and Lazada?

On Shopee Singapore, sellers nominate products for campaign sessions through the Marketing Centre in Seller Centre, and Shopee must approve them. On Lazada, sellers upload products into campaigns singly or in bulk through Seller Center. Both platforms check stock, price and shop standing before accepting a product.

 

According to Shopee's Product Campaign nomination guide, a few rules shape the whole plan:

 

• Approval is not automatic. Nominations can be rejected for stock issues, prices that miss the campaign criteria, or penalty points on the shop.

• Some campaigns screen out shops with penalty points. A poor fulfilment record in October can cost you a slot in November.

• The window closes. Sellers cannot add products after the nomination period ends, though approved products can be opted out.

• Bulk nominations have limits. Excel uploads are capped at 1,000 product variations per file.

• One session per product. You can nominate a product for several campaigns, but it is approved for only one session at a time.

 

Shopee may also suggest products and prices for you to confirm. The discount cost on those recommendations is borne by the seller, so a partner checks each one against your margin floor before approving.

 

On Lazada, Lazada University covers how to upload products into campaigns one at a time or in bulk through Seller Center. A partner running both stores keeps one price sheet so the same product is not priced differently by accident.

 

 

What happens inside the store during the campaign window?

During the campaign window, the partner runs the store live: watching sell-through on hero products, moving stock between channels, raising or pausing ad budgets, answering buyer chat, and escalating payment or listing errors. On Shopee Singapore, recent double-date sales have opened at 8pm the night before and run for more than a week.

 

That opening hour is often the busiest of the whole campaign. Shopee's own 11.11 deals page describes the 8pm launch as the peak window when the biggest vouchers and flash deals go live.

 

A typical live-operations rota looks like this:

• Before launch: confirm vouchers are active, prices have switched, and stock counts match the warehouse.

• First two hours: check sell-through every 15 to 30 minutes and top up stock on fast movers.

• Ads: shift budget from weak keywords to products that are converting, and cap spend on items close to selling out.

• Chat: answer delivery and voucher questions quickly, since unanswered chats lose sales during short flash windows.

• Errors: fix wrong prices, broken variations or stuck orders before they spread.

 

Stock is the most common failure point. When the same unit is listed on Shopee, Lazada and TikTok Shop, a slow sync can sell it twice. Our upcoming explainer, What Is Inventory Sync, and Why Does Overselling Happen?, explains how to prevent this.

 

How do you protect store health when orders spike?

Protect store health by shipping inside each platform's deadline. Shopee Singapore asks sellers to keep their Late Shipment Rate below 5%, measured over the past seven days, and issues penalty points above that. For standard delivery, orders placed by 2pm must ship the same day, and later orders by the next working day.

 

Those rules come from Shopee's Late Shipment Rate guidance and its shipping deadline FAQ. Sellers with a high number of penalty points in a quarter can have seller privileges suspended, which can include losing access to future campaigns.

 

A partner protects store health in three ways:

9. Matching promotions to capacity. Discounts are sized to what the warehouse can pick, pack and hand over each day.

10. Running fulfilment on campaign hours. Extra shifts start when orders land, not the next morning.

11. Watching the metric daily. Late shipments are caught in hours, not discovered in the weekly report.

 

The warehouse side of this, from labour hours to wave picking, is covered in our sibling guide on campaign-day fulfilment for a 5x order spike. For the preparation checklist, see our peak season fulfilment checklist for Singapore sellers.

 

What should you hand to a partner, and what should you keep?

Hand over the repeatable, time-critical work: nominations, voucher and ad setup, live monitoring, chat, stock allocation and fulfilment. Keep the decisions that define your brand: final pricing floors, which products to push, budget caps and approval of any discount beyond an agreed limit.

 

Clear decision rights stop the most common campaign-night problem: nobody is sure who can change a price at 9pm.

Task	Partner runs it	You approve or own it
Product range and hero SKUs	Recommends based on data	Final choice
Discount depth and price floors	Models margin scenarios	Sets the floor
Campaign nominations	Submits and tracks approval	Informed
Vouchers, bundles, ads	Builds and adjusts live	Sets total budget cap
Stock allocation per channel	Runs daily	Approves major shifts
Chat and buyer issues	Handles to agreed scripts	Escalations only
Pick, pack and dispatch	Runs end to end	Informed
Post-campaign report	Prepares	Reviews and decides next steps

Conclusion

Campaign day management turns 11.11 and 12.12 from a scramble into a plan. The work starts about six weeks out, runs through platform nominations and live monitoring, and ends with a clean wind-down before the next sale.

 

The stores that do well treat promotions, stock and shipping deadlines as one system. Whether you run it in-house or with a partner, set clear decision rights early and size every discount to what your fulfilment can actually ship.

Frequently Asked Questions

 

How early should I prepare for 11.11 on Shopee Singapore?

Plan to start about six weeks before. Campaign nominations close before the sale and products generally cannot be added afterwards, so range, pricing and stock decisions need to be made early.

 

Can a partner join Shopee campaigns on my behalf?

Yes, a partner with access to your Seller Centre can submit nominations, build vouchers and manage ads for you. You should still own the seller account and agree in writing who approves prices and budgets.

 

Why was my product rejected from a Shopee campaign?

Shopee lists common reasons as stock issues, prices or products that miss the campaign criteria, and penalty points on the shop. Fixing fulfilment performance before nominations open improves your chances.

 

What happens if I ship late during 12.12?

Late shipments raise your Late Shipment Rate. On Shopee Singapore, a rate above 5% over the past seven days earns penalty points, and a high total in a quarter can lead to suspended seller privileges.

 

Is campaign day management worth outsourcing for a small store?

It often is when the same few people handle listings, ads, chat and packing. Peak days stretch a small team across all of them at once, which is where late shipments and pricing errors usually happen.
